§ 25.263 Information sharing requirements for SDARS terrestrial repeater
operators.
This section requires SDARS licensees in the 2320-2345 MHz band to share
information regarding the location and operation of terrestrial repeaters
with WCS licensees in the 2305-2320 MHz and 2345-2360 MHz bands. Section
27.72 of this chapter requires WCS licensees to share information regarding
the location and operation of base stations in the 2305-2320 MHz and
2345-2360 MHz bands with SDARS licensees in the 2320-2345 MHz band.
(a) SDARS licensees must select terrestrial repeater sites and frequencies,
to the extent practicable, to minimize the possibility of harmful
interference to WCS base station operations in the 2305-2320 MHz and
2345-2360 MHz bands.
(b) Notice requirements. SDARS licensees that intend to operate a new
terrestrial repeater must, before commencing such operation, provide 10
business days prior notice to all potentially affected Wireless
Communications Service (WCS) licensees. SDARS licensees that intend to
modify an existing repeater must, before commencing such modified operation,
provide 5 business days prior notice to all potentially affected WCS
licensees.
(1) For purposes of this section, a “potentially affected WCS licensee” is a
WCS licensee that:
(i) Is authorized to operate a base station in the 2305-2315 MHz or
2350-2360 MHz bands in the same Major Economic Area (MEA) as that in which
the terrestrial repeater is to be located;
(ii) Is authorized to operate base station in the 2315-2320 MHz or 2345-2350
MHz bands in the same Regional Economic Area Grouping (REAG) as that in
which the terrestrial repeater is to be located;
(iii) In addition to the WCS licensees identified in paragraphs (b)(1)(i)
and (ii) of this section, in cases in which the SDARS licensee plans to
deploy or modify a terrestrial repeater within 5 kilometers of the boundary
of an MEA or REAG in which the terrestrial repeater is to be located, a
potentially affected WCS licensee is one that is authorized to operate a WCS
base station in that neighboring MEA or REAG within 5 kilometers of the
location of the terrestrial repeater.
(2) For the purposes of this section, a business day is defined by
§ 1.4(e)(2) of this chapter.
(3) For modifications other than changes in location, a licensee may provide
notice within 24 hours after the modified operation if the modification does
not result in a predicted increase of the power flux density (PFD) at ground
level by more than 1 dB since the last advance notice was given. If a
demonstration is made by the WCS licensee that such modifications may cause
harmful interference to WCS receivers, SDARS licensees will be required to
provide notice 5 business days in advance of additional repeater
modifications.
(4) SDARS repeaters operating below 2 watts equivalent isotropically
radiated power (EIRP) are exempt from the notice requirements set forth in
this paragraph.
(5) SDARS licensees are encouraged to develop separate coordination
agreements with WCS licensees to facilitate efficient deployment of and
coexistence between each service. To the extent the provisions of any such
coordination agreement conflict with the requirements set forth herein, the
procedures established under a coordination agreement will control. SDARS
licensees must maintain a copy of any coordination agreement with a WCS
license in their station files and disclose it to prospective assignees,
transferees, or spectrum lessees and, upon request, to the Commission.
(6) SDARS and WCS licensees may enter into agreements regarding alternative
notification procedures.
(c) Contents of notice. (1) Notification must be written (e.g., certified
letter, fax, or e-mail) and include the licensee's name, and the name,
address, and telephone number of its coordination representative, unless the
SDARS licensee and all potentially affected WCS licensees reach a mutual
agreement to provide notification by some other means. WCS licensees and
SDARS licensees may establish such a mutually agreeable alternative
notification mechanism without prior Commission approval, provided that they
comply with all other requirements of this section.
(2) Regardless of the notification method, notification must specify
relevant technical details, including, at a minimum:
(i) The coordinates of the proposed repeater to an accuracy of no less than
±1 second latitude and longitude;
(ii) The proposed operating power(s), frequency band(s), and emission(s);
(iii) The antenna center height above ground and ground elevation above mean
sea level, both to an accuracy of no less than ±1 meter;
(iv) The antenna gain pattern(s) in the azimuth and elevation planes that
include the peak of the main beam; and
(v) The antenna downtilt angle(s).
(3) An SDARS licensee operating terrestrial repeaters must maintain an
accurate and up-to-date inventory of its terrestrial repeaters operating
above 2 watts average EIRP, including the information set forth in
§ 25.263(c)(2), which shall be available upon request by the Commission.
(d) Calculation of Notice Period. Notice periods are calculated from the
date of receipt by the licensee being notified. If notification is by mail,
the date of receipt is evidenced by the return receipt on certified mail. If
notification is by fax, the date of receipt is evidenced by the notifying
party's fax transmission confirmation log. If notification is by e-mail, the
date of receipt is evidenced by a return e-mail receipt. If the SDARS
licensee and all potentially affected WCS licensees reach a mutual agreement
to provide notification by some other means, that agreement must specify the
method for determining the beginning of the notice period.
(e) Duty to cooperate. SDARS licensees must cooperate in good faith in the
selection and use of new repeater sites to reduce interference and make the
most effective use of the authorized facilities. SDARS licensees should
provide WCS licensees as much lead time as practicable to provide ample time
to conduct analyses and opportunity for prudent repeater site selection
prior to SDARS licensees entering into real estate and tower leasing or
purchasing agreements. Licensees of stations suffering or causing harmful
interference must cooperate in good faith and resolve such problems by
mutually satisfactory arrangements. If the licensees are unable to do so,
the International Bureau, in consultation with the Office of Engineering and
Technology and the Wireless Telecommunications Bureau, will consider the
actions taken by the parties to mitigate the risk of and remedy any alleged
interference. In determining the appropriate action, the Bureau will take
into account the nature and extent of the interference and act promptly to
remedy the interference. The Bureau may impose restrictions on SDARS
licensees, including specifying the transmitter power, antenna height, or
other technical or operational measures to remedy the interference, and will
take into account previous measures by the licensees to mitigate the risk of
interference.
